To all whom t may concern.:

Be it known that I, RUDOLPH C. G. S'rAA'rs OELs, a citizenV oit' the United States, and resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Vacuum Containers, ot' which the following' is a specification.

The principal object of this invention is to provide a new and improved construction in a vacuum container which will enable the samecontainer to be used to carry both hot and cold fluids or other material at `the same time and to prevent heat exchanges between the diliferent materials as well as between the contents of the containei` and the surrounding atmosphere.

Another object is to lprovide a vacuum container with a stopper having a vacuum chamber and a compartment to hold a 'freezing mixture.

A further object is to provide the stopper with a resilient means adapted to contact with the cover of the container and torce the stopper downwardly under pressure against the top of the contents of the container, and n another object is to provide a Vmovable partition of such a construction that a double vacuum will be provided .tor dividing or in; sulating the container into compartments.

For the accomplishment of these and such further objects as will hereinafter be apparent to those skilled in the art to which this appertains, the invention consists in the construction, combination and arrangement of parts herein speciiically described and illustrated in the accompanying drawings, wherein is shown a preferred embodiment of the invention, but it is to be understood that changes, variations and modiiications may be resorted to which tall within the scope of the claims hereunto appended.

In the drawings forming a portion of this specification- Fig. 1 is a central section through a container embodying my invention.

Fig. 2 is a top view of the container shown in Fig. 1 with the cover removed and a portion of the container shown in section.

As shown inr the drawings, the numeral 10 indicates the outer side walls of the main body of the container between which and the inner side walls v11 a suitable space 12 is dei-ined. The side walls 10 and 11 are suitably joined together at the top as by the annular portion 13, which with the side walls 10, 11 andthe bottom portions 14 and 15 completely enclose the space 12, it being understood that the air is exhausted trom said space by any suitable means after which the container is 'hermetically sealed.

Ehe container is shown in the drawings as of cylindrical shape but it will be understood' that any desired shape, size or configuration may be resorted to and that the manner of constructing the same or the material used obviously can be varied as desired.

rlhe inner walls 11 and bottom portion 14 define the material holding chamber ot the container and both sides of the walls as well as the other portions of the body of the container are preferably coated thoroughly with a heat insulating paint or coating.

A cover 16 which is also preferably provided with a vacuum chamber 17 is hinged as at 18 to the container body and is provided with any suitable latcliing means such as indicated at 19.

A partition is provided for the purpose ot dividing the material holding chamber into separate compartments as indicated by the numerals 2O and 21 and comprises a lower member 22 provided on its upper face with a recess 23 in whichis received the cooperating projecting portion 24 of the upper member 25. rllie lower and kupper meinbers 22 and 25 are provided with the vacuum chambers 26 and 27 respectively and each.V

of these members are alsopreferably coated with a suitable heat insulating composition. The portion 24 and recess 23 may be provided with cooperating screw threads as inn dicated, or they may be merely secured togetlier by a tight press i'it. Each ot the members 22 and 25 are provided with a projecting annular flange 28 between which is secured a packing 29 of rubber or other suitable material. The dimensions of the iianges 28 and the packing` 29 are so proportioned that the partition will be a tight sliding iit in the material chamber and a handle 30 is provided for convenience in moving the partition as desired.

A stopper 31 is also preferably provided with a vacuum chamber 32. `The lower face of the stopper 31 is provided with a depending annular portion 33 which is preferably detachable from the stopper 31 about `which is adapted to be engaged a cup member 34, suitable cooperating projections and depressions indicated generally by the numeral 35, being provided for holding the cup 34 in ber into the compartments 2O and 2l.

detachzdile engagement with the annular portion 33.

Suitable means for holding the stopper firmly pressed against the contents `of the container may be provided and comprise a pair of stirrup braces 86 suitably secured to the upper face of the stopper, between which and the upper face of the stopper is slidably held a bowed fiat spring` 3'?. `When the cover 1'? is closed lupon the stopper, the upwardly bowed portion oit the spring 'Swill beengaged by the `cover and will place the spring under` tension, thereby nrgingthe stopper *downwardly into 'the chamber oi the' container. lllhcnthc cover is opened, the bowedporticn or the sjn'ingwill serve as a handle iterA removing `the stopper. lt will be Anoted' that' the'ends otthef springs' are curved upwardly as at Sie to prcvent'the spring trom being' pulled out of thebraces ldwlien itis usci as a handle, to remove the stopper.v

The manner in which the container is adapted tor use is as follows, assuming that it is desired yto carry orpreserve 'a quantity-4 oi" both hot and Cold liquids or materials for a considerable'time without a great Vamount or heat exchange as for instance, coliee and ice cream on a picnic or outing. coliie-ewill preferably be placed in thematerial chamber iirst after which the partition will be placed in the chamber until Vit contacts with the lfluid, thus' dividing the cham- The compartment '2l may then' be illed with ice cream for example, thedouble vacuum of the 'partition effectively preventing any Y heat exchange between the materials in thecompartments.` Obviously any number of partitions may be used.v

If a substance which'it is desired to'le'iep' cold is placedin the upper compartmentl, a quantity/'of' a freezing" Vmixturesuch as ice and salt 1s 4placedwithin the 'cup andthe spring'l pressingrthestopper -31 downwardlywill prevent anair cushion being formed' between the stopper and contents and will also cause thein'fluence of the tree ing mixture to be more effective.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent ot the United States', is :we
